Noncommutative synchrotron [PDF]

open access: yesPhysical Review D, 2004
We study the departures from the classical synchrotron radiation due to noncommutativity of coordinates. We find that these departures are significant, but do not give tight bounds on the magnitude of the noncommutative parameter. On the other hand, these results could be used in future investigations in this direction. We also find an acausal behavior

Imaging Regional Lung Structure and Function in Small Animals Using Synchrotron Radiation Phase-Contrast and K-Edge Subtraction Computed Tomography

open access: yesFrontiers in Physiology, 2022
Synchrotron radiation offers unique properties of coherence, utilized in phase-contrast imaging, and high flux as well as a wide energy spectrum which allow the selection of very narrow energy bands of radiation, used in K-edge subtraction imaging (KES ...

SYNCHROTRON POLARIZATION IN BLAZARS [PDF]

open access: yesThe Astrophysical Journal, 2014
We present a detailed analysis of time- and energy-dependent synchrotron polarization signatures in a shock-in-jet model for gamma-ray blazars. Our calculations employ a full 3D radiation transfer code, assuming a helical magnetic field throughout the jet.

A Single-Particle Trigger for Time-of-Flight Measurements in Prompt-Gamma Imaging

open access: yesFrontiers in Physics, 2020
Tracking of single particles accelerated by synchrotrons is a subject that crosses several physics fields. The high clinical intensities used in particle therapy that can exceed 109 p/s make this task very challenging. The tracking of the arrival time of

Synchrotron total-scattering data applicable to dual-space structural analysis

open access: yesIUCrJ, 2021
Synchrotron powder X-ray diffraction (PXRD) is a well established technique for investigating the atomic arrangement of crystalline materials. At modern beamlines, X-ray scattering data can be collected in a total-scattering setting, which additionally ...

Gold Standard for macromolecular crystallography diffraction data

open access: yesIUCrJ, 2020
Macromolecular crystallography (MX) is the dominant means of determining the three-dimensional structures of biological macromolecules. Over the last few decades, most MX data have been collected at synchrotron beamlines using a large number of different

Glycoscience@Synchrotron: Synchrotron radiation applied to structural glycoscience [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2017
Synchrotron radiation is the most versatile way to explore biological materials in different states: monocrystalline, polycrystalline, solution, colloids and multiscale architectures. Steady improvements in instrumentation have made synchrotrons the most flexible intense X-ray source.
